To all whom tmay-ooiwem:

Beitknown thatI', AUGUSTUS A. BALL, Jr acit-izen of the IJnited States,and a resi: dent of Bronklyn' county of Kings, and Stateof- New York,have invented a new and,;usefnl Improvement in Typographical OflSiiInghi lChlIleS,;Of which the following is a specification..-

My invention has r-e'ference to typographical casting machines, such forinstance as linotypemachines; wherein a slug or bar is cast in a slottedmoldagalnst a composed line of matrices,- -wh;ich ispresented tempo:

rarily to the front the mold and serves to form the type characters onthe edge of the slug. In this class of machines, as represented forexample in U. S. Letters Patent to O. Mergenthaler, No. 436,532, theslug is delivered from the mold by an ejector blade, which advances fromthe rear and moves the slug before it out of the mold and into areceiving galley.

In order to adapt the machine for producing slugs of different lengths,the mold slot is made variable in lengthby the use of interchangeablefilling pieces or liners, such as are shown for instance in U. S.Letters Patent to G. A. Bates, No. 618,554. When the length. of the moldslot is thus changed, the ejector should be also changed, and this iseffected by detachingit and substituting another of a widthcorresponding to the new length of the slot. v

In practice it occasionally happens that an attendant, through ignoranceor carelessness, will substitute a wide ejector without inserting ashort liner, or that he will insert a long liner without changing theejector. In such case, when the ejector advances, it will contact withthe inner end of theliner and drive it-forward. As the liner isordinarily providedwith a transverse rib which is seated in a groove inthe mold body, the result will be the breakageofthe expensive mold, dueto the strength of the liner and the great leverage exerted therebyunder such 'condit ions.

The aim of my invention is to prevent accidents of this character, andthis is effected. by the provision of a member which is adapted to yieldin the event of undue strain thereon. Preferably, the liner is themember selected for such improvement, and more specifically the resultis secured by lessening its resistance, so that it will be moved orTYPOGRAP ICAL CASTING-MACHINE Specification of Letters .I'atent.

I have herein shown mv; invention as ;ap

plied by way ofexan plei n-a preferred form, and'obviously many changesand variations may be made therein without. departingfrom its spirit. II therefore desire ;-it to be. disin so far as such limitations arespecified in tinctly understood that I do not limit myself to anyspecific form or embodiment except perspective view of a mOld-havinginyins vention applied thereto Fig:. 2 is a perspec-' tive view of theliner detached;Fig. 3' is a top plan view of the niold-with the cap .de:tached and illustrates the?manner infiwhich an ejector of too greatwidth acts uponthc yielding liner.

Referring to the drawing, the mold consists of the body portion A, thecap B secured thereto, and liners interposed between the body and cap,whereby the slot D may be regulated both as to length and height, in themanner well understood in the art and as substantially illustrated inthe Bates patent previously mentioned. In order to prevent the breakageor bendingof the eXpen-- 'sive mold or of the ejector blade E, in theevent that the latter is too wide to pass through the inold slot D, Iprovide a yielding member, which in the specific example shown is theliner C. This liner in most respects is substantially the same as theone illustrated in the Bates patent, it being formed with a slot C andwith a transverse rib G which latter engages'in a corresponding groovein the mold body. This rib serves as a means for determining thelongitudinal adjustment of the liner and also for preventing the linerfrom turning or twisting horizontally. If therefore the ejector blade E.

be too wide'to pass through the mold slot I), and therefore contactswith the liner, ordinarily and due 'to the strength of the latter andthe considerable leverage exerted there-- by, the mold itself will. bedeformed or broken. It is therefore preferable to form the liner so thatit will yield and be bent in the event of undue strain being impartedthereto, and this result I secure by recessing it, as at C, at apointinside of the rib C .to provide an integral and permanentlyweakened portion which is yieldable in the event that suflicientpressure be exerted on an edge'ot the liner.

The operation of the" parts is clearly shown in FigaB, it being notedthat the ad vanceof the ejector blade E acts merely to bend the liner,instead of allowing the latter to eXert'its destructive leverage uponthe mold in the manner previously indicated. It should be. noted thatthisweakening or recessin-g of the liner .does not otherwise afiect its,functions, as at the rear side thereof it presents a continuous surfaceof the ordinary extent and ofsufiicient strength to close tightly any'holes in the potmouth which may lie behind it. v

- ,As before indicated, he broad idea of the. invention .is' theprovision ofa yielding '-'*member for the purposes specified, andobviously its selection, location and construction may be va'ried inmany-ways that will suggest themselves to those skilled in the art.Having thus described my invention, its construction and mode ofoperation, what'I claim and'desire to secure by Letters Patent of theUnited States is as'follows:

I 1. A mold liner consisting of an integral structure formed ,offracturable material and having in oneedge a permanent recess extendinginwardly toward the opposite,

liner is engaged by an ejector, said liner being providedwith'a-transverse rib at one side of and adjacent the recess.

- 3.. In a typographical casting machine, the mold comprising a bodyportion, a cap, and a mold liner consisting of an integral structureformed of fracturable material and having in one edge a permanent recessextending inwardly toward the opposite edge, thereby providing apermanent reducedportion which is yieldable Whenever the liner isengaged by an ejector.

'In testimony whereof I hereunto. setmy hand this 13th day of December,1911, in the presence of two attesting witnesses.
